Tony Nitrous thanks for the Brocks link in your clutch topic!

I am not a mechanic like some of you, so I had to read all of Brocks info since I am
interested in bettering my personal ETs on the strip...yet not making a drag bike out of
the good riding King. These pages are good...maybe I won't tear up the competition
but don't want to tear up the King either.

King is a little different but Brocks system approach makes
sense....and clutch is part of it.

Edit: Interesting...his thinking on -1 front sprocket allowing lower RPM
launches...saving clutch plates and then rolling on power.
Must try that instead of higher RPM starts.

Better to go bigger on the back, the tighter you wrap the chain, power is lost more at the wheel and the more stress it put on the chain/ tranny. Add links to keep your wheel base longer.

I like how they sell 9.6 with some riding skills but don't mention rider weight at all. A bucks a buck.

Its my understanding the new v-max does not fair as well as expected, mainly because of the reported heavier weight. How much weight is it?

125lbs- Thanks Tony. approx 25lbs worth a tenth would be approx 5 tenths but then there is a reported 8 more horses and 12 ftlbs torque, that should be worth a tenth- tenth & 1/2. Should be somewhere around 4-3.5 tenths. This is close to the report but is also corrected and only one view.

You note the zuk has 3 yrs unlimited warranty, where is that at?

Interesting though.

go with brocks system i have it on my bike it gave me alot of power i got the full race system and powercomander and x-tre from brocks and im at 190 hp at the wheel sounds good feels good spins 1 and now second all the way now i need a new tire

This thread is about the brocks clutch mod.

Max- I have just over 100 passes now and no signs of problems

Guys,

The how to slam and prep articles were produced in 2001, but the same general guidelines also apply today to the Gen 2 Hayabusa and B-King. We simply have newer parts such as the ultra clutch mod, window links and various style exhaust systems. All of our new exhaust systems have benefited from the knowledge learned starting with the Gen 1 Busa development in 1999.

FYI: I weighed about 160 pounds in leathers at the time and the bike made around 170 (STD scale) rear wheel horsepower as tested. Our local track is 860 feet above sea level . I could squeak into the 9.30s on occasion and run consistent 9.40s.

I now weigh 215+ in my leathers and have been a best of 9.26@154 on my 2008 Hayabusa, using the same guidelines with a RWHP right at 200 STD. There is no doubt I can run a 9.18 or 9.19 in good conditions with my head on straight in the riding department.

Check out this video from Valdosta on my 2007 ZX-14: http://www.brocksperformance.com/media/brock_920.wmv

My Busa makes about five more horsepower and is easier to ride at the track, but an excessive workload keeps me away from practicing. I've only made a handful of passes this year ... but my business is thriving!

loud pipes,
Yes...and no...

The problem is the look. Because the OEM cans are so large, our popular megaphone style systems look out of place (at least to me) under the stock tail section.

We finished a slip on design using our oval mufflers, but there have not been enough requests up to this point to justify a production run.

Quite frankly, we are a bit late on the release of the B-King systems and if it weren't for the fact that they are basically retrofitted Hayabusa systems, we probably still wouldn't have any.

I think they are one of the coolest bikes ever, but unfortunately we have dealers with units still sitting on their show room floor which arrived in 2008. It's hard for us to get excited about a full line of systems for this particular model. The fact that it will not be released in 2010 is also a problem from a new product standpoint.

I'm afraid the B-King may fall into the "limited edition" syndrome which will not allow a large variety of aftermarket parts.

The good news is that most of our Hayabusa systems will also fit the B-King, so we do have quite a few items available.

I will check out our current development status and try to update you soon.

Would have been nice with a Brocks under the tail system that is lighter and give more power than stock.........
With the Busa system the bike might look a bit strange since it is supposed to have the under tail one?
Thanks for your good products, will install the clutch mod I got from you shortly.
Cheers.

Might want to do your clutch mod with exchanging out the slipper clutch.......but I have a big question as far as safety.......




When downshifting I saw on your site that you might hear and/or feel rear tire chirping, would you not want to run this on the street if this bike is also a every-day rider?


I dont want to enhance rear wheel slippage when riding, that kind of issue could get you killed.

rogue007,

We have sold many thousands of clutch mods for street/race use since 1999 with ZERO safety complaints or issues.

All it does is make the clutch work like all other clutches have since the beginning of time .

If you are a hard core road racer, I would suggest using the slipper clutch.

I was glad I had one during the 08 Busa world press release at Road America it was insane to try to slow such a heavy bike at those speeds (tagged 186 limiter on the front straight): http://www.dragbike.com/dbnews/anmviewer.asp?a=3355&z=3

For the street; it provides poor surface feel, ruins any chance of a dead stop launch and can actually DAMAGE parts if you decide to head to the drag strip?!

in the instuctions for the ultra clutch mod, it said there may some filing involved on the input shaft. for you guys that have performed this mod, was there any filing involved? if not, i will order one. i do not like the slipper clutch very much at all.

I will install it next week, I got one that says PN: S13-CM-Ultra 1999-2007 Hayabusa.
The importer where I buy some stuff said it was for my B-King 08 as well, hope this is right, maybe I just got one with an old label?
Very excited to find out if this mod will help me at the drag strip in 2 weeks time.
Last time I had lot of difficulties to launch this beast, probably because I`m a novice but could also be a combination that the clutch is not the best for launching?
Would love those BST wheels you sell Brock, tried to find out the shipping cost to Australia but with no luck, any idea?
Cheers.
